M-1894 Steyr/Mannlicher Self-Loading Pistol of the "blow forward" design.




These early Mannlicher pistols were designed by Ferdinand Von Mannlicher and were produced by the Austrian Steyr factory. Mannlicher was an exceptional early engineer and designer who teamed with the Steyr factory to produce all of his rifle and pistols from the late 1890's through post WWII.

The pistol uses a special rimmed cartridge in 6.5 mm caliber. The design represented an entirely new utilization of mechanical principles in an automatic action called "blow-forward action". In the standard type of automatic action for low-powered cartridges, the recoil (or blow-back) is utilized to drive back a movable breech face or block, but Mannlicher utilized the principle of a rigid standing breech with the barrel blowing forward to extract, eject, and prepare for reloading.

A special barrel housing which carries the front sight, covers the entire length of the barrel (6.49 in/165 mm) when the arm is closed. A heavy recoil spring is mounted concentrically around the barrel within this housing and is compressed between a shoulder at the forward end of the casing and a shoulder at the rear of the barrel.



It is also a "double action" mechanism with a rebounding hammer, a cartridge can be in the chamber with the hammer down, you just pull the trigger as in the double action mode, just like many pistols today. Very unique for "1894".

Another interesting feature is that the pistol looks like it should have a standard removable pistol clip, however it actually has a permanently installed internal magazine that loaded from the top of the action via a stripper clip, when the barrel is forward.
